    摘要:

    從駕駛員視角出發(fā)，構(gòu)建汽車行駛軌跡跟蹤數(shù)學(xué)模型，運(yùn)用Matlab/Simulink工程軟件和C語(yǔ)言，建立駕駛員-環(huán)境-汽車閉環(huán)系統(tǒng)仿真模型。利用Matlab平臺(tái)遺傳算法（GA）仿真包，以駕駛員道路跟隨精度、車輛側(cè)向加速度和轉(zhuǎn)向盤忙碌程度所構(gòu)成的綜合評(píng)價(jià)指標(biāo)為目標(biāo)函數(shù)進(jìn)行分析，獲得模型參數(shù)最優(yōu)值。模擬和試驗(yàn)結(jié)果表明：模型設(shè)計(jì)合理，能較好地反應(yīng)熟練駕駛員正常駕駛特征。

    Abstract:

    In this paper, a driver model based on the driver's heading angle was set up, and with the application of Matlab/Simulink and C language, the driver-environment-vehicle closed-loop simulation model was developed. The model was simulated with the genetic algorithm(GA) toolbox on the Matlab platform. The model parameters' optimal values were obtained by an object function of the genetic algorithm, which comprehensive evaluation index considers the task performance, driver's physical workload and mental pressure. The simulation and experimental results showed that the design of model is reasonable, and the model can describe the driving character of the sophisticated driver.
